Briefing orbs disappear for a short while when someone else picks them up. They respawn within 3-5 minutes. In the meantime they are missing from the spot. You might have visited that spot while it was respawning.

While the locations match the names, the order seems to be off. The order in game is:
1. The Lois Lane from Spot #6.
2. The Lois Lane from Spot #4.
3. Vicki Vale from spot #5.
4. Jack Ryder from spot #2.
5. Lex Luthor from spot #1.
6. Superman from spot #3.

Does it really matter if the order is off, as long as they are all there? I mean, there have been a few that I’ve noticed are out of order but I just wait until I collect them all and then look at them in order.

Well if someone hasn’t done any then no the order doesn’t matter. However, in cases where there are say 8 briefings and someone is only missing one then having the correct listing can save alot of time and energy so I thank Axterix for his correction, while of course thanking genius bunches as well for doing the original work ^_^

That is not true. As you might, or might have not, noticed we have created a furniture database with the housing patch and updated with new collections and briefings as we came across them. We do have less time to work on this website, but we do invest time in it as much as we can.
